Abstract: A method of operating a terminal device and network infrastructure equipment in a wireless telecommunications system for communicating on a primary cell supporting a primary component carrier on radio resources within a first frequency band and a secondary cell supporting a secondary component carrier on radio resources within a second frequency band. The infrastructure equipment establishes a plural configuration settings for the secondary carrier based on measurements of radio usage in the second frequency band, which are conveyed to the terminal device. The terminal device makes channel quality measurements for the secondary component carrier according to the different configuration settings and reports these to the infrastructure equipment. Based on the measurements of channel quality for the different configurations, the infrastructure equipment selects one of the configuration settings, and conveys an indication of this to the terminal device in association with an allocation of transmission resources on the secondary component carrier.

Abstract: The present invention relates to a method for selecting a cell of a wireless cellular communication network (100) having a plurality of cells (111-115). According to the method, a cell size information representing a size of an area served by a cell (111-115) of the plurality of cells is received by a user equipment (106). The received cell size information is transmitted from the user equipment (106) to a base station (105) of the wireless cellular communication network (100) by which the user equipment (106) is served. A cell (111-115) of the plurality of cells is selected for serving the user equipment (106) based on the cell size information.

Abstract: The invention is directed to systems, methods and computer program products for discontinuous signaling in a mobile communication network. User equipment (UE)/mobile terminal requests slotted transmissions and, in response to the network authorizing slotted transmissions, communication of subsequent UE transmissions are slotted, such that a minimum time period is required to elapse between each UE transmission. In specific embodiments of the invention the minimum time period is a predetermined time period known in advance to the user equipment and network. In other embodiments of the invention the user equipment slotted transmission requests includes a requested minimum time period, which may be approved or revised by the network. In still further embodiments the network, upon receiving the request for slotted transmissions, determines the minimum time period.

Abstract: A cellular multiple-input and multiple-output, MIMO, system (10) comprises a base station (20) having a plurality of antennas (22) and a logic (21) which analyzes pilot signals received from a terminal (11-15) at the plurality of antennas (22) to obtain information about radio channel properties between the terminal (11-15; 100) and the plurality of antennas (22). The base station (20) assigns at least two terminals (11-13) of a plurality of terminals (11-15) to a same pilot time slot. The base station (20) requests at least two terminals (11-13) to transmit pilot signals in the allocated pilot time slot in such a manner that the at least two terminals (11, 12; 11-13) are prevented from transmitting their pilot signals simultaneously.

Abstract: A base station (11) for a wireless radio network (10) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and a user equipment (16). The base station (11) receives at each antenna (12) of a subset of the plurality of antennas (12) a training signal sent by the user equipment (16) in a first frame (20) and determines an antenna configuration parameter for each antenna (12) of the subset of the plurality of antennas (12) based on the training signal received in the first frame (20) for a subsequent transmission of payload information (33, 34) between the base station (11) and the user equipment (16) in a second frame (30) which is different from the first frame (20).
